Gyula Fora commented on FLINK-3358:
-----------------------------------
I think this is a good idea but I am not completely sure about the default
behaviour whether it should be HDFS. I would assume memory backend would be
similarly frequent.
We can probably have the single string constructor backed by file state
backend, or the other possibility would be to add static methods like:
RocksDBBackend.withMemoryBackend(Path)
RocksDBBackend.withFsStateBackend(Path)
What do you think?
> Create constructors for FsStateBackend in RocksDBBackens

> I think no user understands what they are supposed to do when they should
> define a "backing state backend".
> The most common thing will probably be that the RocksDB snapshots are backed
> up to HDFS and that this is also the backing state backend.
> A simple constructor with a single URI/Path/String that configures both at
> the same time should be added, to make this accessible to users.
